WO OD WOBKENG-MACHINE Application filed August 30,

To all whom iv' may concern:

Be it known that I, n'rni J. Joncnnr', residing in Sheboygan Falls, inthe county of Sheboygan and State of Visconsin, have invented new anduseful Tmprovements in l'lfoodworking'-Machines, of which the following`is a description, reference being` had 'to the accompanying` drawings,which are a part of this specification.

This invention relates to improvements in woodworking` machines, andmore particularly to that class known as planers.

One of the obj eots of said invention is to provide a woodworking`machine especially adapted for planing or dressing t-he surface oflumber such as boards and the like, said machine being` simple inconstruction, strong` and dni-able, and easily adjusted.

Another object is to provide means for planing lumher of varyingthickness and widths simultaneously. i

Another object is to provide simple means for adjusting the machine tomake cuts, in planing, of varying` thickness.

A further object is to provide means for alining' the cutter.

A still further object is to provide means whereby the cutter is mademore easily accessible for sharpening` and repairs.

A still further object is to provide means for raising` and lowerin` thefeed rolls without interfering with the power transmission to saidrolls.

lVith the above, and other incidental objeots, in view the inventionconsists of the machine and parts or their equivalents, as hereinafterdescribed.

in section; and, Fig. 10 is a detail in section of parts shown in Fig.9.

Like numerals of reference refer to corresponding parts throughout thedifferent. views of the drawings.

The reference numeral indicates the main supporting frame, which may bemade of any uitable size or shape but is preferably cast in a singlepiece for strength and rigidity and is rectangular in horizontal plane.

The frame is provided with bearing brackets 16-16 integral therewith andextending forwardly and rearwardly of the front and rear portionsrespectively of the said frame, and these bearing brackets are adaptedto support ournal boxes 17-17 disposed thereon. A shaft 18 is journaledin said bones and provided with. a number of longitudinally disposedknives 19-19 bolted thereto forming` the cutter of the machine. TheCutting edges of these knives are positioned equidistant from the centerof the shaftso that when the cutter is revolved all of the knives willcome into Cutting engagement with the surface being' planed.

A belt pulley 20 is fastened to one end of the cutter shaft 18 and isadapted tobe driven with a belt (not shown) in the usual manner. Thelower surfaces of the ournal boxes are inclined and rest upon adjustablewedge blocks 21-21 the upper surfaces 22-22 of which are correspondinglyinclined so that when the wedge blocks are moved in one direction thejournal boxes and the cutter journaled therein will be raised, and whenmoved in the opposite direction, the journal boxes and the cutterjournaled therein will be lowered, and by moving only one of the wedgeblocks, the cutter may be properly alined with the surface upon whichthe material to be planed rests. The lower' portions of the wedge blocksare semi-circular in cross section and fit in correspondinglysemi-circular depressions 23-23 in the brackets 16-16 so that theinclined surfaces of the wedge blocks will always coincide with theinclined lower surfaces of the journal hoxes in any position ofadjustment. The semi-circular depressions 23-23 are longer than thewedge blocks 21-21 to allow an endwise movement of said blocks inadjusting` the height of the ournal blocks, and in order to move saidwedge blocks, adjusting bolts 2-2-Lt threaded in the upwardly extendinglugs 25-25 of the brackets 16-16 and bearing against the ends of saidwedge blocks, are provided whereby a very fine adjustment of the cuttermay be made' VVhen the cutter is properly alined the j ournal blocks aresecurely fastened to the brackets by means of bolts 26-26 which passthrough openings in the brackets 16-16, through slots 27-27 in the wedgeblocks 21-21 and are threaded into the lower portions of the journalblocks. The slots 27-27 in the wedge blocks permit of the said blocksbeing moved endwise by means of the bolts 24-24 when the bolts 26-26 areloosened.

A bed-plate 28 provided with elongated tongues resting on ways on theupper portion of the main frame is adjustably secured thereto by meansof clamping bolts 29-29 passing through slots 30-30 in the bed-plate andthreaded to the main frame. Other bolts 31-31 also pass through saidslots and are threaded to the main frame and serve to more securely holdthe bed plate in position on the main frame. A lever 32 pivotallyconnected at one end to the main frame and medially to one end of aconnecting link 33 is disposed beneath the bed-plate near one end. Theother end of the connecting link 33 is pivotally connected to thebed-plate by means of a pivot bolt 34 thereby providing convenient meansfor adjusting the position of the bed-plate on the main frame withrelation to the cutter.

Two standards 35-35 bolted to the bed plate 28 and connected together attheir upper ends by a cross piece 36 form a slideway for supporting asectional feed roller frame 37 adjustably mounted thereon. This framewhich consists of two side blocksV 38-38 dovetailed to the standards soas to be freely moved up and down by means of adjusting screws 39-39threaded to said side blocks, are connected together rigidly by an angleiron 40. The forwardly projecting portion of the angle iron 40 serves asa guard to prevent the fingers accidentally coming in contact with thecutter or feed rollers while feeding material to the machine. Theadjusting screws 39-39 pass through openings in the cross piece 36 andare supported and have their bearings therein. Miter gears 41-41 mountedon the upper ends of the adjusting screws 39-39 and in mesh with themiter gears 42-42 mounted on a horizontal shaft 43 extending across themachine above the standards and having bearings in lugs 44 extending upfrom the cross piece 36 are adapted to be revolved by means of the handwheel 45 mounted on the forward end of the horizontal shaft, to adjustthe height of the sectional feed roller frame above the bed plate, toaccommodate lumber of different thicknesses.

A feed shaft 46 having bearings in both side blocks of the sectionalfeed roller frame is provided with a number of sprocket Wheels 47rigidly connected thereto, and each sprocket wheel is provided with asprocket chain 48 which passes around a section of a feed roller 49having sprocket teeth 50 formed thereon. Each feed roller is looselymounted on a short shaft 51 carried by a swinging pressure member 52pivotally supported on the shaft 46. Each swinging pressure memberconsists of two side arms 53-53 joined together at their forward ends bya cross piece 54 integral therewith. The forward ends of the sidemembers rest upon the angle iron 40 which serves as a stop to limit thedownward movement of the pressure members. The rearward portions of thetwo side arms are inclined upwardly and are provided with elongatedslots 55 to accommodate elongated nuts 56 loosely mounted on the feedshaft 46 on both sides of each V=,pro-cket wheel 47 and passing throughsaid slots. The nuts fill the slot transversely but not longitudinally,thereby permitting the pressure frame to be moved forwardly withrelation to the power shaft 46 to take up slack in the chains caused bywear. The pressure frames are moved by bolts 57-57 passing looselythrough bolt holes in the rearward ends of said frames and threaded intothe nuts 56. As the bolts are tightened the rear ends of the side armswill be advanced towards the power shaft 46, and the feed rollsconnected to the forward portions of the side arms will be moved awayfrom the power' shaft, thus tightening the Chains. The feed rollers aresolid to provide sufficient weight to cause said rollers to positivelyfeed the lumber to the cutter, and to prevent said rollers from slippingthereon, the peripheries thereof are serrated or toothed, the serrationsalso extcnding across the end of the sprocket chain teeth formed p 011said rollers.

By forming the usual feed roll into a plurality of independently rotatedand swinging rolls it is possible to feed lumber of differentthicknesses and widths to the machine at the same time without anychange of adjustment or any Variation of cut in planing.

A large sprocket wheel 58 connected to the rear end of the feed shaft 46is provided with a sprocket chain 59 which depends therefrom and engagesa small sprocket wheel 60 mounted in a rectangular swinging frame 61.The rectangular swing frame 61 is suspended by means of a link forinedof two yokes 62 and 63 and an adjustable connecting rod 64 reverselythreaded on its ends which engage threaded openings in both of theyokes. The connectiing rod is provided with a lock nut 65 to lock thesaid rod to the lower yoke and prevent its accidental rotation. Theupper yoke 62 is pivotally connected to the feed shaft 46 on both sidesof the sprocket wheel 58 and the lower yoke 63 is pivotally connected tolugs extending upwardly from the rectangular swinging frame G1.

The rear portion of the rectangular swinging frame G1 is pivotallymounted on a driving shaft G6 which has its bearings in the main frame.A small sprocket wheel 67 is mounted on the driving shaft 66 between theside members of the rectangnlar frame 61 and is provided with a sprocketchain 68 which surrounds a large sproeket wheel (39 connected to a shortshaft 70 journaled in the forward portion of the rectangnlar f'ame 61.The sprocket wheel 60 is also connected to this shaft.

By means of the yokes and the connecting link, the swinging rectangularframe, and the sprocket Wheels and chains, it is possible to raise andlower the sectional feed roller frame, and to slide the bed plate andthe sectional feed roller frame carried thereon rearwardly to adjust thecutter without stopping the rotation of the feed rolls as theconstruction permits the feed shaft being moved Vertically andhorizontally without changing the distance apart of the chain connectedshaft Centers.

1he driving shaft GG has loosely mounted thereon a drive pulley 71located beneath the bed-plate which is driven in the usnal manner by abelt (not shown). The drive pulley is adapted to be connected to thedriving shaft by means of a clutch member T2 'o Je'rated b i a oivotedfoot lever T3 in the ordinary way.

An adjustable feed-plate 74: mounted on cranked rock shafts 75 and 76which have their bearings 77-77 in the main frame is disposed above themain frame and in front of the rotatable cutter. The feed plate isprovided with guide strips 78-78 to guide the lumber being planed in theproper direction.

The front ends of the cranked rock shafts have connected thereto disks70 and 80 and to these disks are connected, pivotally` threaded blocks81-8l. A connecting rod 82 reversely threaded at its ends is connectedto said blocks. Another threaded block 83 is pivotally connected to thedisk 80 and to this block is threaded a screw bolt 84 provided with ahand wheel 85 for rotating the same. The bolt 8% has its bearing` in ablock 8G which is pivotally connected to a bracket 8? connected to themain frame. The feed plate is raised or lowered to increase or diminishthe depth of the cut in planing by turning the hand wheel 85 which willrevolve the disk 80 and by means of the connecting rod 82 will likewiserevolve the disk 79, this will cause both cranked shafts to move and thecranked portions thereof upon which the feed plate is mounted will beeither raised or lowered as the case may be,

depending upon the direction of rotation given to the hand wheel.

As the inner edge of the feed plate is beveled off and is positionedabove a portion of the cutter and as close as possible thereto it isnecessary, in lowering the plate, to also move it away from the cutterto prevent its being struck by said cutter. The construction asdescri'bed accomplishes this result by means of the cranked shafts whichin lowering the plate also move it away from the cutter, the arc ofniovement of the cranked shafts being the same the radius of the cntterso that the inner edge of the feed plate will be substantially the samedistance from the cutting edges of the knives in all ordinary positionsof adjustment.

In order to level or align the feed plate with the bed plate the opening88 of the bearing which surrounds the cranked portion of the crank shaft(5 is elong'ated so as to permit an independent movement of this shaft,which movement will tilt the feed plate to any angledesired. Thisindependent movement of the crank shaft 7 5 is accomplished by turning`the connecting rod 82 which will revolve the disk 79 and the connectedcrank sha 't 7:3, the crank shaft 70 being held in adjusted position bymeans of the bolt 8a and the disk 80.

Tn operation, the different parts of the machine are adjusted andpositioned as shown in the drawings .and boards being placed on the feedplate and pushed beneath the feed rolls will be drawn along over thecutter which will plane or dress the under surface of the boards to adepth corresponding to the distance the top of, said feed plate ispositioned beneath the plane of the top of the radius of the cutter. nfeeding lumber of different thickness to the machine, the different feedrolls will be raised different distances and will Continue to feed theboards in the same manner as before described. lVhen boards which arethicker than the distance between the feed plate and the angle iron areto be planed, the sectional feed roll frame is raised a proper distanceby means of the hand wheel and the miter gears. Tf it is desired toreplace a knife or examine the cutter, the hand bolts clamping the bedplate to the main frame are loosened and the bed plate with the feedroll frame carried thereon is moved rearwardly by means of the handlever beneath said plate. The feed plate is also moved away from thecutter and lowered by means of the hand wheel and crank shafts whichwill allow clear access to the cutter. f it is desired to adjnst theheig'ht or angle of the cutter, this may be done by means of theadjustable wedge blocks and adjusting screws. The sprocket chains on thefeed rolls may be adjusted Or tightened by means of the adJustingscrews, and all of these adjnstments may be made While the machine is ladj ustable vertically With relation thereto, a

in operation.

From the foregoing description it Will be seen that the machine issimple in construction and operation and all necessary adjnstments areprovided for.
